This exercise allows a user to load one of two CSV files and then perform histogram analysis and plots for select variables on the datasets. The first dataset represents the population change for specific dates for U.S. regions. The second dataset represents Housing data over an extended period of time describing home age, number of bedrooms and other variables. The first row provides a column name for each dataset. The following columns should be used to perform analysis:  PopChange.csv:  Pop Apr 1  Pop Jul 1  Change Pop Housing.csv:  AGE  BEDRMS  BUILT  ROOMS  UTILITY Notice for the Housing CSV file, there are more columns in the file than are required to be analyzed. You can and should still load each column. Specific statistics should include:  Count  Mean  Standard Deviation  Min  Max  Histogram A user interface might look similar to this: ***************** Welcome to the Python Data Analysis App********** Select the file you want to analyze: 1.

Create a binary attribute Apps01 that contains a 1 if Apps contains a value equal to or above its median, and a 0 if Apps contains a value below its median. Create a single data set d containing both Apps01 and the other College features. Split the data into d.train training set and d.test test set 80:20.b. Perform k-NN with several values of k in order to predict Apps01 using all the features.c. Display the comparison of validation error rate for different values of k.
Provide a function named getFromSessionStorage that will retrieve the object you put in session storage with the previous function. Your function should accept a "storeName" parameter and return the object it retrieves. Note: The remaining buttons and paragraphs do not have id attributes.

Examine the following code. function getData() { var url = "ajaxdata/citStudents.txt"; var request = new XMLHttpRequest(); request.open("GET", url); request.onreadystatechange = function() { if (request.readyState == 4 && request.status == 200) { alert(request.responseText); } }; request.send(null); } What does it mean if the condition (request.readyState == 4 && request.status == 200) evaluates as true? it means there were no http errors and that the data has been returned to the browser. it means there were was an HTTP error and that the data will not be returned to the browser. it means the request has been sent and data will be back in 200 milliseconds or less.
Consider this code. Assume the axios files have been loaded from the CDN, and that our HTML includes a div element with an id='display'. function getQuote() { axios.get('http://ron-swanson-quotes.herokuapp.com/v2/quotes') .then( function(response) { quote = response.data[0]; document.getElementById('display').innerHTML = quote; }) .catch( function(error) { status = "An error occurred: " + error; }); } Why do we ask for the first element in the data array, data[0]? Because no matter what web service we request data from, that web service will always return a array of with a single element. Because we investigated the ron-swanson-quotes API, and it revealed that a request like the one we made returns an array with a single element. That element would be in index 0.

In R please provide the code and steps for the following Install the dplyr package and load the library. Load the starwars data set Make a new dataframe that only contains the height and species columns from the original data set Remove all of the rows from the new dataframe that have missing values. How many rows of data were lost when the n/a values were removed? It is recommended that you use the na.omit() function for this ex: myData <- mydata %>% na.omit() Create two new dataframes that contain the heights of humans and aliens (not humans and not droids) respectively. Read the help documentation for the par() function – the first example listed is especially relevant. Create 4 images in the same window Top Left : histogram of human heights Top Right: histogram of alien heights Bottom Left: qq plot of human heights Bottom Right: qq plot of alien heights Describe the shape of the distributions and what your observations are about the heights of these two…
